Sentencing is set for September 10th where each of them are facing a minimum of 10 years to life in prison and/or a $10 million dollar fine.

Fernando Guerra, Sr. admitted to being a predatory drug traffic or using corrupt law enforcement officers to steal drugs from rivals.

Fernando Guerra, Jr. admitted to using corrupt officers and his family's trucking company to ship drugs north.

Federal court records show that the father and son are forfeiting seven properties in Hidalgo and Willacy Counties in order to get a lower sentencing recommendation.

With their pleas, some 10 out of the 12 suspects have pleaded guilty.
